The Environmental Protection Agency, which polices chemical contaminants, has been subjecting employees at its Chicago offices to water contaminated with metal and Legionella, the bacteria that causes the deadly Legionnaires’ disease.

The Chicago Sun-Times reported this week that at least five water fountains or kitchen faucets were found to have Legionella. Two kitchen faucets also busted the acceptable limits for lead and copper.

In Michigan, meanwhile, another federal building was found in 2017 to have a high risk of fire, and experts said it needed a sprinkler system. Seven years later, the problem remained unaddressed, an inspector general found.
